摘  要:
基于FVCOM(Finite Volume Coast and Ocean Model)模式,建立了舟山海域台风风暴潮增水数值模型。通过对1509号台风"灿鸿"进行风暴潮过程模拟,验证了模型可用于舟山海域的台风风暴潮增水的模拟和分析;以1509号台风为基础,构造了9条不同路径台风分别进行风暴潮增水模拟,得到了对舟山岱山县沿海最有利增水的台风路径;在最佳路径的基础上,叠加五种不同强度的台风场,分析不同强度台风作用引起的增水情况;应用此模型探讨了未来情景下平面上升30cm和上升66cm后的水位极值分布情况以及其相对于原始海平面的变化情况。

摘  要:
Using the FVCOM A numerical model,Zhoushan sea storm surge was established.It was proved that the model was suitable for the simulation and analysis of storm surge in Zhoushan sea area by simulating the storm surge caused by Typhoon No.1509.Based on Typhoon No.1509,nine different tracks were designed to simulate the storm surge,and the maximum surge increase track was found.Based on the most dangerous track,five different levels of intensity of the typhoon were designed to analyze typhoon storm surge at different intensities.Using the storm surge model constructed in this study,analyzing the extreme value of typhoon storm surge and determining the changes compared to the original sea level in 2050(MID)and 2100(long-term)sea level were our future goals.
